`BERT R. BENJ'VAI'IIN, OF OAK PARK, ILLINOIS, ASSIGNOR TO INTERNATIONALI HARVESTER COMPANY OF NEW JERSEY, A CORPORATION OF NEW JERSEY.

GRAIN-HARVESTER.

Specification of Letters Yatent.

Patented Nov. 9, 1915.

To-aZZ whom it may concern Be it known that I, BERT It. BENJAHIN, acitizen of the United States, residing at Oak Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Grain-Harvesters, of which the following is a full,clear, and exact specification. V

My invention relates to grain harvester-S, and is particularly designedfor use 1n the harvesting of Kafir corn.

'I`heob3ect of my invention is to provide an improved mechanism thatwill separate the butts of the stalks from the heads and bind them inseparate bundles for greater convenience inthe handling of the shock.

A further object of my invention is to provide an improved mechanism ofthe character set forth which is adapted to use in connection with agrain binder of standard construction.

rIhese objects are attained by means of mechanism, one embodiment ofwhich is illustrated in the accompanying drawings, in which--` Figure 1is a rear elevation partially in section of part of a grain harvesterhaving my invention embodied in its construction; Fie. 2 is a sideelevation of Fig. 1; and Fig. 8 rs a detail view of the stationary knifemember.

Like reference characters designate the same parts throughout theseveral views.

The harvester includes the usual grain platform 1, wheel frame 2,elevator 3, traction wheel 4, and crank shaft 5, which may derive motionfrom the traction wheel in any preferred manner.

6 represents a grain binder carried by the wheel frame, and 7 the binderdeck leading from the delivery end of the elevator to the bindingmechanism.

8 represents a common form of binder frame, having a needle shaft 9 andknotter shaft 10 journaled therein, motion being imparted to theseshafts in any preferred way.

11 represents the usual knotter head, and l2 the knotter actuating gear,13 the dischar e arms, 14 the breast-plate, and 15 the need e; theseparts being common in grain binders. A

For the urpose of my invention, the nee-A dle shaft 1s provided with arearward extension 16,' and the knotter shaft is extended rearwardlyalso.

17 represents a supplemental knotter mechanism carried by the rearextension of the knotter shaft, and the same in all essential elementsas the one heretofore described; the mechanisms being separated by meansof the sleeve member 1S, and 19 represents a supplemental needle thatcooperates with the supplemental knotter.

Q0 represents packer arms moving in or- Y bital paths, that derivemotion from the packer shaft 21 in a common way and operate adjacent theneedles.

For the purpose of severing the stalks between the knotter' mechanisms,a suitable knife is provided. In the embodiment of my invention shown, aknife 22 in the form of a packer arm having a sharpened stubbleward edgeis used. This knife is located between the two packers 20 and preferablyderives motion from the )acker shaft, as shown, although it may e drivenindependently from some operative part of the machine. Cooperating withthis moving knife, as shown in Figs. 1 and 2, is a fixed coacting knife23 carried by a bracket 24 secured to the binder deck and projectingupwardly from the latter. (See Figs. 1 and 3.)

In operation the stalks are delivered to the packers and knottingmechanism as in common forms of grain binders, and as they are beingpacked against the trip arm and compressor the movable knife 22,cooperating with the opposing knife 23, severs them between theknotters, thus separating the butts of the stalks from the heads.

It is to be understood, however, that I disclaim the broad combinationof the spaced or axially alined knotting devices with means for severingthe stalks between them,

or an orbital knife for so cutting the same operating either alone or incooperation with a fixed knife in such a manner as to sever the stalksin advance of the knotting devices. Nevertheless, while I have shown anddescribed a preferred form of my invention, I do not wish to confine itto the specific details as described, except as limited by the abovedisclaimer, as many minor changes may be made without departing from thespirit of my invention.

`What I claim as my invention, and desire to secure by Letters Patent,is:

1. Incombination, mechanism for forming a prostrate bundle, bindingmechanism for binding said bundle at a. plurality of points, and meansfor severing the stalks in said bundle at a point between said bindingmechanisms.

2. In combination, a binder deck, a plu 'rality of knotting devicesspaced apart above the same, and means carriedbeneath lsaid deck andmovable therethrough for cutting the stalks between said knottingdevices. 3. In combination, a binder deck, a. plurality of knottingdevices spaced apart above the same, a knife movable through said deckat a point beneath said knotting devices, and an upstanding stationaryinember on said deck cooperating with said knife. 4. In a grain binder,a'frame, a binder deck, a plurality of knotting devices carried abovesaid deck, packing mechanism on said frame cooperating with saidknotting devices and movable through said deck, and means operativelyconnected to said packing mechanism for severing the stalks between saidlinottingr devices.

. 5. In a grain binder, a frame, a binder deck, a plurality of alinedknotting devices spaced. apart above said deck, packing-mechanismcarried on said frame cooperating with said knotting:r devices andmovable through saiddeck, a knife for severing the stalks between saidknotting,r devices, and knife driving knife and said packing mechanism.

Ina grain binder, a frame, a binder deck,a plurality of alined knotting devices spaced apart above said deck,packing mechanism coperating with said knotting devices and movablethrough 'said deck, a' knife for cutting the stalks betweensaid knottingdevices pivotallyconnected to said frame, and knife driving connectionsbetween said knife and packing mechanism.

7. In a grain binder, in combination, a plurality of axially alinedknotting devices spaced apart, a binder deck, packer arms operativeabove said deck and adjacent each' of said knotting devices, a packerdrivingshaft, and a knife driven by said packer driving,r shaft andoperative to sever the I stalks between said knotting devices.

I'n agrain binder, a binder deck, a plurality 4`ofaxially alinedknotting devices spaced apart thereon, packer arms opera.- .i tive abovesaid deck and adjacent each of said knotting devices, a packen drivingshaft beneath, said deck, a knife driven by; said shaft,`and acoperating fixed knife carried bysaid binder deck coperalting with saidmovable' knife' in severing the stalks between said knotting devices.

In testimony whereof I afiix my signature, in the presence of twowitnesses.
